Ask yourself.. what are aliens made of if they are different from us and how long did it take their evolution to get it done if the environment was different?

There are good reasons why life didn't form. Peptide and nucleotide bonds need to form from amino acids before proteins can form. This means the input of energy with the release of water....alternations of heating snd cooling, wetting and drying for chain length extensions. All this in the...

New technologies can be and are being developed on Earth. No need to bring back a few rocks from Mars.

Yes, one of the motives is to stop spending massive amounts of the taxpayers money on what has become a "wild goose chase" That's illogical. The Mars missions have been a spectacular technological success, but a failure at the basic reason for using that technology....finding evidence for life...

The original question was real. "Is there life on Mars?" But now it's not about life but all about habitability billions of years ago because they have found zero evidence of any cellular carbon at all. Bringing back a few essentially randomly selected rocks will not change that. The odds are...

Whoa.. " and decide to say that scientists are wasting money trying to understand something that is real." That's the whole point.. they have been spending years (and giga$$$$) trying to find out if life on Mars was real...actually there. And have come up with a blank. This is not a video game...

The Mars program has now basically become a make-work program for all those who would be out of work if NASA didn't keep looking for life. Finding that billions of years ago Mars could have been habitable is all that they could legitimately conclude. So wasting money going back to pick up some...

This lengthly search for life on Mars has gotten way too expensive. To date there has been no evidence of any cellular remnants of microbial life. Sandstones and silts, but no laminated shale or slate rocks where organic carbon would most likely be found. No organic carbon fossils such as...

No.. the planet is 70% water and was never covered with magma and volcanoes. That's why we are here.

Records like never before? 1.5°C warming would be 15.5°C. or 59.9°F. Back in 1988 Dr. James Hansen from NASA testified to the US Congress that the global temperature was above the 1950-1980 average of 59°F. That's above 15°C. which is above the pre-industrial average of about 14°C. So today's...

The fact remains that Percy hasn't the on-board technology to evaluate the Martian sediments as does Curiosity, Makes it much more difficult to find any evidence of life, much less past life.

Agree.

Percy doesn't have the ability to recognize and confirm the presence of fossilized organic cellular remains, carbon that would help prove there was life on Mars billions of years ago . Everything else is a proxy.

The rovers were not sent to find out if conditions for life were there billions of years ago. They were sent to study the rocks to search for life or some actual evidence it was there. So far nothing has been found and only two samples have actually been taken and x-rayed. by Curiosity. None...

The only way to be sure that there was life on Mars (or anywhere) is to find fossil organic carbon residues that are found even in the oldest rocks on Earth. The remains of cellular organic matter preserved in martian sediments. And even that could be from carbonaceous chondrite meteorites that...
